PROCESS OF PRESERVING FGOD.

SPECIFICATION forming part of Letters Patent No. 317,673, dated May l2, 1885.

Application iiled March 2, 1885.

.Z'o all whom t may cori/cern, .1

Be it known that I, ALEXANDER GUSTAV TI-IEoDon RIPBERGER, of Dresden, in the i Kingdom ot' Saxony, Germany, have invented i certain new and uset'ul Improvements in the ,Preservation ot' Provisions, &o., oi' which the following is a specification.

Difficulty is experienced in protectingl great bulks ot' provisions-such as for military or 1o naval or other purposes-against injuriousinucnces tor a long period, even it' such provisions consist ot' thoroughly baked and comparatively dry goods. Moisture, deposit and spreading oi't'ungi, spores, microbes, calandre, I5 and other vermin are known to be destructive to provisions. Endeavors have been made to protect the provisions during storage, either by the hermetical exclusion ot' air or by inanual treatment-that is to say, by taking the zo provisions out ot the boxes or other receptacles, and to dust or clean them, thereby countei-actin g, periodically, the in j urious iniiuences. There are hardly any energetic and reliable means knovvuor in use by which vermin, out side or inside ol" the provisions, are entirely rel moved; at the same time, hardly any means are known that att'ord perfect security against l vermin, moisture, Src., affecting the provisions.

The present invention consistsin providing 3o means for eii'ecting the above speciiied object.

The method employed, according to this invention, consists, in the first instance, not to hermetically exclude the air 'from the provis-A ions, but to provide means t'or the air to reach the provisions in a filtered state or condition 5 and in the second instance, to use the filter i employed Within the walls of the receptacles as a protection against the approach ot' vermin, Sac., byimpregnating such filter and walls 4o with certain substances. lt is to be understood that neither the ingredients for such im pregnation, nor the method in which it is apA plied, will prove injurious to the provisions.

in using this method, the receptacle t'or provisions-that is to say, sacks, casks, boxes, or barrels, of wood or tin-is lined inside with a. i layer of Ybers. ll prefer to use cotton-wool t'or this purpose, and to im pregnate the cotton Wool with a liquor, as hereinafter specilied. 5o This application of a layer oi' impregnated cotl ton-Wool is doneby means of double sacks, it l (No specimens.)

' sacks are the receptacles employed i'or the provisions. lll boxes, casks, Sto., are employed, the layer ot' the impregnated cottonu'ool is put ou the inside ot' the reeeptacle,a1'1d is 55 thereafter covered by means oi" coarse i'abric or pasteboard or glazed board or veneer.

All receptaclesl made of Wood Will offer ready access to the air by means ot' the joints, which generally increasein width during storage. it' the. joints in such receptacles are very close or tight, holes may be bored in to top, bottom, or sides of such receptacles. It such receptacles are made oftin or other metal, the'walls, tops or bottoms iuay be suitably 65 pierced, all such holes or joints beingI covered inside by the abovemeutioned inside filteringlayer. lf baked provisions are packed for storage in a Warm condition or state, and a change oi' temperature takes place within the recepta- 7O cles by cooling or otherwise, the outer air will enter into the receptacle; but this outer air, which Would carry the destructive germ to the provisions in the form of fungi, spores, microbes, &c., will be perfectly filtered by nieans 75 ot'thelayer oi'cotton-Wool, and will only comein contact with the provisions in its liltered state.

The impregnation of the cotton-wool layer and ot' the material used l'or constructing the re- 7 ceptacles will furthermore prevent the cater- 50 pillar ot` the Tineo. granella, and mites (known as the worst enemies oimilitary and naval provisions) will not penetrate the impregnated layers. As all these insects and all sorts of coarse vermin have a disgust or aversion against bitter substances and salt, l prefer to choose an impregnating'liquor composed of such substances. I take ten parts ot' castorleaves, (folic Victim) ten `parts of laurel leaves, (fol/1d laura) ten parts of three-leaf 9O leaves, f'oli'c tri/elite) live parts of green wal nut-shell, (cori/cis 'nacionjuglandfd) live parts oit1 gentian root, (Radix gea'crnag) cut the same and extract them by one hundred and titty f parts ot water, which is poured on boiling, and

which is allowed to extract in a closed vessel during about an hour. This extract is after terWard-iiltered through woolen bags, and then fifteen parts at' common salt are dissolved iu it. This liquor i use at a temperature of about 50o 100 centigrade (1220 Fahrenheit) to impregnate the cotton-Wool layer, which shall be used as the Carriages for i storage'houses, will be sutliciently treated by a double wash with the boiling liquor.

In dressing sacks for the above-mentioned y purpose-that is to say, to make them suital ble for receiving provisions-I proceed as follows: The impregnated sack is lined inside l by a layer of impregna-ted cotton-wool of about three-fourths ot' an inch thick, and a second sack. not impregnated and preferably without seams, is inserted into the lined outer sack. It may be well to stiteh these three layers toi gether, but it may suffice to stitch the layer of l impregnated cotton-wool to the outer or to the inner sack, or to attach it thereto in any suitable Way. The inside sack is made so much shorter at top that the outer sack with the cotton-wool lay er will suffice to effect the closure of the sack, for which purpose I prefer to use a. short cylinder of wood, impregnated in the liquor and covered with impregnated cotton-wool. Against this cylinder the top of the outer sack withitslayerofcotton-wool is bound,

quick. as possible from the influence of the atmosphere.

In using carriages for transport, which are fitted out in the above-described manner, I recommend to provide all joining or closing faces with tongue and groove, and to insert a loose plait of impregnated cottonwool into the groove. ln these carriages t-lieloose cooled provisions-such as bread, biscuit, lard, Ste.- 1 are tightly stored, and the coverof the carriage is closed by wedges, bars, or turn-buckle.

Although in the foregoingdescription the new method ot1 packing and storing has been described as especially employed for military and naval provisions, it is obvious that nearly all other other eatables, seeds, grains, and grocers7 and druggists1 ware may be permanently preserved and stored in the described manner against any outer injurious intluences.

Although the abovenamed substances for producing the impregnating liquor have organic bitter substances is not excluded, and may be used without departingfrom the main feature of this invention.

There is no necessity for handling the provisions during any period or length otstorage, therefoie there will be no loss by breakage, Ste.

The r eeptacles may beclosely stored, therefore, in a given space. In using the above-described method of packing', larger quantities may be stored than heretofore.

This method will insure for army and navy thoroughly healthy and nice provisions.-

and I prefer to provide a sufficiently deep horizontal groove in the wood cylinder into which groove the folds of the outer sack will be lodged if the sack is closed by string or other suitable means. sack will be protected against all named outer injurious intiuences.

In using boxes, casks, or other wooden receptacles, I proceed by covering the inside of the walls (sides, top, and bottom) with a layer of impregnated cotton-wool, this layer being fastened to the walls by a diluted solution of glue. This cottouwool layer I afterward cover by pasteboard, glazed board, sackcloths, or veneer, which are fastened by nails or any other suitable means. The parts of the cover forming the closingjoint receive layers of imthe receptacle cotton will .join on cotton.

The provisions inclosed in this In storing baked provisions for military, naval,-or other purposes, I recommend to store y them in the, receptacle while still in a` warm condition, and immediately thereafter to close the receptacles, in order to withdraw the provisions imniediately after leaving the oven as Ido not claim inclosing the provisions to be preserved in cotton cloth,cotton-Wool, sawdust, or other substances saturated with a preservative compound, such as described in English Patent No. 6,134 of 1882.

l claim as my invention- The method specified for protecting provisions of al1 kinds during storage against the noxious or injurious influence of moisture and against the intrusion ot' vegetable or animal organism by storing such eatables or provissions without the hermetical exclusion of air, in sacks, boxes, or other receptacles lined with a layer of a filtering medium-such as cotton-wool--impregnated with a bitter eX- tract and salt, and the material of such recep. tacles being also impregnated with such bit-ter substances and salt, substantially as specified.

ln testimony that Iclaim the foregoing as my invent-ion I have signed my name in presence ot two subscribing witnesses.
